After designing and deploying a WLAN infrastructure, you notice that co-channel interference (CCI) is causing poor performance in the 2.4 GHz band. Although the WLAN was primarily designed for 5 GHz, 2.4 GHz was included as a best-effort solution. You discover that the implementers did not follow your configuration guidelines.
What can you do to minimize the impact of CCI in the 2.4 GHz band without adding adjacent-channel interference (ACI)?
